Captcha with Altcha

With the open source solution ALTCHA, a data protection-compliant and barrier-free alternative to CAPTCHA has been integrated.
ALTCHA is a security mechanism that helps to distinguish human users from automated computer programs and serves to protect your website.

Instead of having to laboriously solve puzzles or enter illegible sequences of letters, a simple tick in a checkbox is now sufficient to identify yourself as a human being.
